摘　　要：推动黄河流域高质量发展,必须增强流域内耕地和粮食安全的保护力度。基于标准耕地系数修正的耕地压力指数模型,从黄河流域和地市的两个视角出发探究2005—2021年流域内耕地资源与耕地压力时空演变特征。结果表明:(1)黄河流域耕地压力指数值波动下降,空间分布格局呈现出“整体布局稳定、局部变动”基本态势,压力重心呈东西方向振荡变化,整体向西北迁移;(2)地市耕地压力异质性明显、离散程度加大、空间布局极化现象明显,耕地压力时间序列呈倒“N”或“波动”型分布,空间格局表现为中游压力集聚特征;(3)黄河中上游地市耕地压力过重、下游地市压力增长均需引起政府部门的重视,以期通过政策调整、科技投入等措施增加耕地面积与粮食单产,实现高效现代化农业。To promote high-quality development of the Yellow River Basin,it is necessary to enhance the protection of cultivated land and food security within the basin.Based on the modified cropland pressure index model with standard cropland coefficients,this paper investigated the spatio-temporal evolution characteristics of cultivated land resources and cultivated land pressure from the perspective of the Yellow River Basin and urban areas from 2005 to 2021.The results showed that:①The value of cropland pressure index fluctuated and decreased in the Yellow River basin.The spatial distribution pattern showed a basic trend of“stable overall layout and local changes”.The center of gravity of pressure showed an oscillating pattern of east-west changes,with the overall migration to the northwest.②The heterogeneity of cultivated land pressure in each city was obvious,the degree of dispersion had increased,and the phenomenon of polarization of spatial layout was obvious.The time series of cultivated land pressure in each municipality showed an inverted“N”or“fluctuating”type distribution.The spatial pattern of cultivated land pressure in each municipality was characterized by the clustering of pressure in the middle and upper reaches.③The pressure on cultivated land in the upper and middle reaches of the Yellow River was too heavy,and the pressure in the lower reaches of the Yellow River continued to grow,all of which needed to attract the attention of the governmental departments,in order to increase the area of cultivated land and grain yields through policy adjustments,scientific and technological inputs,and other measures,so as to realize high-efficiency and modernized agriculture.
